Introduction: Anti-Cyclic Citrullinated Peptides (CCPs) are a well known diagnostic and prognostic noble marker for rheumatoid arthritis. C-Reactive Protein (CRP) is an acute phase protein whose level rises in response to inflammation.
Aim: This study was undertaken to show the role of the two markers (anti-CCPs and CRP) in autoimmune skin disorder and their association with associated arthritis in these disorder.
Materials and Methods: Serum anti-CCP antibodies and CRP was measured in 50 patients of autoimmune skin disease of which 28 were of psoriasis, 12 of Systemic Lupus Erythematosus (SLE) and 10 of Pemphigus Vulgaris (PV). These patients were categorised in two groups, with associated arthritis and without arthritis. The serum level of anti-CCP and CRP was correlated with the presence or absence of arthritis in these patients. Control group consists of 20 healthy subjects in which these two parameters were measured.
Results: Out of total of 50 patients, anti-CCP was raised in 36.37% of patients with associated arthritis and 12.82% of patients without arthritis whereas CRP was raised in 63.63% of patients with arthritis and 35.89% of patients without arthritis. Mean serum anti-CCP in patient with arthritis was 15.78±13.94 U/ml and without arthritis was 7.56±7.68 U/ml with p=0.01 which was statistically significant. Mean serum CRP in arthritis was 21.11±15.51 mg/l and CRP without arthritis was 13.14±12.27 mg/l with p=0.07 which was statistically not significant.
Conclusion: Although both anti-CCP and CRP are valuable markers for autoimmune skin disorder, anti-CCP seems to show significant association with arthritis.
